Heat & Glo direct vent gas appliances are designed to
operate with all combustion air siphoned from outside of
the building and all exhaust gases expelled to the outside.
No additional outside air source is required.
Installation MUST comply with local, regional, state and
national codes and regulations. Consult insurance carrier,
local building inspector, fire officials or authorities having
jurisdiction over restrictions, installation inspection and
permits.

• Where the appliance is to be installed.
• The vent system configuration to be used. If Passive

opening in relation to venting and other construction

service technician, service agency or your dealer.
